Answer:
No, she is not correct, this is a proportional relationship.
Step-by-step explanation:
Proportional relationships are relationships with equal ratios
column 1 column 2 column 2/column1
'x' 'y'
1 5 5
2 10 5
5 25 5
10 50 5
As we clearly see that ratio of column 2 and column 1 is same for every row
Therefore, the given relation is proportional.

Using the normal distribution, it is found that 2.64% of all the nails produced by this machine are unusable.
In a <em>normal distribution</em> with mean
and standard deviation
, the z-score of a measure X is given by:
- It measures how many standard deviations the measure is from the mean.
- After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.
In this problem:
- The mean is of 3 inches, hence
.
- The standard deviation is of 0.009 inches, hence
.
Nails that are <u>more than 0.02 inches</u> from the mean are unusable, hence:



The proportion is P(|Z| > 2.22), which is <u>2 multiplied by the p-value of Z = -2.22</u>.
Z = -2.22 has a p-value of 0.0132.
2 x 0.0132 = 0.0264
0.0264 x 100% = 2.64%
2.64% of all the nails produced by this machine are unusable.

Answer:
Step-by-step explanation:
1 quart of wax makes 6 candles
If 30 candles is to be made then 5 quart of wax is needed
The quart is made up of
2 part of red
5 parts of yellow
3 Parts of white
Total= 10 part to make the Orange shade
We knew Yellow is 5 part out of 10 part as written up
Hence, yellow will be 2.5 part in 5 quart
